EFI Tuning,
Built from Scratch_
SGK Embedded Performance designs standalone ECUs, writes the firmware, and tunes them - all in-house. We build the hardware, write the software, and live on the dyno.
Who We Are
EFI Tuning
Real-world calibration across a range of platforms. Not just applying maps, but understanding what the engine needs.
Standalone ECU Design
The EpicEFI platform. Hardware and firmware built from the ground up, not slapped together off a reference design.
Custom Embedded Hardware & Firmware
Anything from sensor boards to custom controllers. If it needs microcontrollers and a clean PCB, that's what we do.
EpicEFI Firmware Contributors
Active development on the EpicEFI platform, open to those who help.
EpicTuner Developer
Our tuning software. Calibration, live telemetry and datalog analysis, with a native plugin SDK to extend your workspace.
We don't do aftermarket parts, intake manifolds, or bolt-on kits. Our product is the ECU and the firmware that runs it.
